Product is ok. Stylish, easy to set and use. Has a lock setting. Filters may have a longer life than others. Cons: The app can't see where I live so the Outside is 30miles off. It's not HEPA. It's not cheap. Ionize technology release ozone (and the app doesn't check for it).

Seems powerful and can be silent when in Smart mode, which I like. It’s a bit bulky, hence why I removed a star, but overall it’s very easy to use. I would have loved if it had a cover on top for when not in use. I need to improvise something to protect against my toddler.

good and quiet, but useless app as it doesn't work well with Google Home. And not at all with Alexa.

The only reason for not giving this 5 stars is because of the price. It cleans the air so quietly. It checks the air quality and speeds up or slows down the fan based on what it finds. As an example, when a smoker returns to the room after a smoke break it detects the residual particles, shows a poor air colour light, and then speeds up the fan to get back to green. Almost magic. And it can all be seen and controlled from the phone.

Having never used an air purifier before, I was skeptical about its benefits. After using the AX91-404GY for almost 4 months, I can "feel" the difference in the air. I suffer from hay fever, allergies and asthma, and this helps in making the air feel clean. Especially after cooking, the air purifier gives off a red light which indicates poor air quality, and in less than an hour the light turns green - which means the air quality is ok. The AX91-404GY is a little bigger than I imagined, but the design and colour is sleek, and it fits well in a modern home. I would like it to be a little smaller so that it wouldn''t take up too much space. It is generally not noisy when running, except for when the air quality is poor, the fan will run a little harder which creates a louder noise (but only for awhile). Very straight forward and easy to use when turned on manually. However, over the months I''ve had issues with connecting to the AEG app. I''ve only knocked a point off because of that. Some of the issues of the app range from the app crashing, or not being able to detect my air purifier, or even after I''ve managed so connect my air purifier to the app, it requires re-setting up when I move my air purifier into another room. Overall, I''ve found the air purifier to be beneficial for my home and health. Apart from the app which needs work, it would have been perfect!

Had item for a month now. Liked it so much, bought two! One for upstairs and one down. Works very well and very quiet. Humidity and temperature are not accurate which is a shame for the price but not a show stopper. No problems with the app and love that I can control it remotely.

Noticed a difference straight away, great looking , low noise would highly recommend

It does everything AEG says it will plus it looks good. It is exceptionally quiet in operation. The particles in my bedroom are reduced to zero even with the door open. The Wellbeing App is great, but takes a long time to load every time it is opened.
